如何将条带式支付与已有的django表单集成，只在支付成功时保存表单

import stripe

        payment_intent = data['object']
        
        if event['type'] == 'payment_intent.succeeded':
            # 支付成功时的处理逻辑，保存表单等操作
            # 在这里可以根据需要调用相关模型的保存方法，如form.save()
            form.save()
        
        return JsonResponse({'status': 'success'})
